WALL-NAIL.

SPECIFICATION forming part of Letters Patent No. 703,704, dated July 1,1902.

Application filed March 18, 1902. Serial No. 98,863. (No model.)

To all whom it may concern:

Be it known that LADAM HOFMANN, a citizen of Germany, residing atMunich, Bavaria, Germany, have invented certain new and usefulImprovements in Wall Nails, Pegs, or Pins; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertainsto'make and use the same.

The present invention relates to wall nails, pegs, or pins; and itconsists in the details of construction hereinafter set forth, andparticularly pointed out in the claim.

In order to render the present specification easily intelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout both views.

Figure 1 is a section through one part of the nail or peg, and Fig. 2 asimilar section through the prolongation of the same.

In driving wall-nails into brickwork the distance to which they aredriven in in order to attain sufficient hold in the wall to support theobject to be suspended depends upon Whether they strike the brick or themortar joint, it being necessary in the latter case to drive the nailfarther into the wall. According to the present invention the nail maybe prolongated, according to the distance it is driven into the wall.

The nail consists of the pointed section a, having a shoulder a and athreaded spindle b extending therefrom. This part of the nail is firstdriven into the wall, and if it proves long enough the head or button 6may be screwedonto the spindle b and the object hung uponit. If,however, the first section has not got sufficient hold-in the wall'thesecond section is attached. The second section consists of a sleeve 0,having an interior thread to fit that of the threaded spindle Z), asindicated at d, and a shoulder c of about the same diameter as the parta at a.

The sleeve c is screwed onto the spindle I) up tothe shoulderja, whenthe compound nail] thus formed may be driven a correspondingly greaterdistance into the wall,

the sleeve 0 having a screw-spindle 19 extending from its shoulder. Anynumber of these sections may be added, and the button 0 is finallyscrewed onto the screw-spindle b, which finally projects from the wall.

In driving the sections in it is advisable to place a piece of pipe ortube over the screwspindle Z; or b, which pipe or tube rests on theshoulder a or c, as the case may be, in order to avoid spoiling thethread, or a bolt having a corresponding boring may be placed over thethreaded spindle to prevent the blows of the hammer from striking theend of the screw-spindle.

I claim as my invention- A wall nail, peg or pin consisting ofaplurality of sections, each having a reduced screw-threaded spindle atone end,one of said sections having its other end pointed, the othersection having an internally-threaded sleeve at the end opposite itsspindle and arranged to engage the screw-threaded spindle of the pointedsection, in combination with a threaded button arranged to engage thespindle of either section.

In testimony whereof I afi'ix my signature
